Question

The area of a triangle with the fixed base equal to 34in depends on the length of its altitude. Write the formula that describes the area of a triangle as the function of its altitude’s length.

Answer 1

A = a(17 in)

Explanation:

The area (A) is given in terms of the base (b) and altitude (a) by the formula ...

A = (1/2)ba

Filling in the given dimension, we have ...

A = (1/2)(34 in)a

A = a(17 in)

__

If the altitude has dimensions of inches, then the area will be in square inches. Otherwise some conversion will be necessary to get the area in square units.

You're probably expected to write this without the units:

A = 17h . . . . if h represents the altitude (height)
